Application filed September 21, 1917. Serial No. 192,588.

To all whom it may concern:

Be it known that we, (1) KATHRYN M. RAY and (2') DAVID HENDRIOKSON,citizens of the United States, residing at (1) Los Angeles, (2) Oakland,in the county of (1) Los Angeles, (2) Alameda, and State of California,have invented certain new and useful Improvements in Liquid-VendingMachines; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to liquid vending machines and more particularlyto machines especially adapted for vending gasolene and oils formotorists use and the primary obj ect of this invention is to provide aliquid vending machine, which upon the deposit of a coin will deliver acertain amount of the liquid to be dispensed.

Another object of the invention is to provide a coin controlled liquidvending machine, which includes a means for receiving a plurality ofcoins of different denominations and for delivering an amount of liquidequal in value to the value of the coin deposited.

A further object of the invention is the provision of a coin controlledliquid vending machine in which the machine for delivering the liquidcan be adjusted so that the amount of liquid to be delivered for a coinof a certain denomination can be regulated according to the fi uctuatingprice of oils and gasolene. v

A still further object of the invention is the provision of a liquidvending machine in which an electrical circuit is closed by a coin,which operates a clutch and allows the pump stem to be operated so thata certain amount of liquid can be pumped therefrom.

A still further object of the invention is the provision of a coincontrolled vending machine, which includes means for automaticallyopening the circuit'when a predetermined amount of liquid has beendelivered, so as to prevent further operation of the pump stem.

A still further object of the invention is the provision of means forautomatically throwing the coin from between a pair of electricalcontacts after a predetermined amount of liquid has been delivered, soas to open the circuit and. prevent delivery of any more of the liquidand to set the machine for the reception of another coin.

A still further object of the invention is to provide a liquid vendingmachine of the above character, which is durable and efficient in use,one that is simple and economical to manufacture and one that can beplaced upon the market at a reasonable price.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter specifically described, claimed and illustrated in theaccompanying drawings, forming a part thereof in which,

Fig. 8 is an enlarged detail view of the coin controlled disk showingthe means for throwing the coin out of the same,

Fig. 9 is a fragmentary detail view illustrating the manner of pivotallymounting out of the tank. The pump stem 3 projects into the rectangularcasing 2 and has a rack bar 4 secured thereto for a purpose which willhereinafter be more fully described.

A plurality of inclined coin chutes 5 ex tend from the upper frontportion of the casing 2 downwardly and through a casing 6, whichincloses any preferred type of coin separating means. This means forseparating the good coins from the slugs has not been described orillustrated as the same forms the subject matter of another invention.Extending from the bottom of the coin separating means 6 is a pluralityof chutes- 7 which are in alinement with the first mentioned chutes andreceive the coins after the same have been tested. It is to beunderstood that the chutes are to receive coins of differentdenominations and are to be so labeled, soas to indicate to the user ofthe device where to insert a coin of a certain denomination and thechutes are here shown to be four in-number and are adapted to receiveten, twenty-five, and fifty cent and one dollar coins, it beingunderstood, however, that any number of chutes can be employed and bemade to receive a coin of any desired value. A fixed shaft 8 ispositioned directly below the lower ends of the chutes 7 and this shaftcarries a plurality of rotatable disks 9 which are positioned inalinement with each one of the chutes 7. Each disk is provided with aseries of equidistant spaced slots 10 which are adapted to partiallyreceive the coins from the ends of the chutes. The upper walls of thechutes 7 are cut away at the lower portions thereof so as to allow thedisk 9 to carry the coins from the chutes when the disk is rotated. 7

Each disk 9 has a projecting hub 11 which rigidly carries a ratchetwheel 12 and rotatably carries a gear 13. The gear 13 carries a pivotedspring pressed pawl 14 which is adapted to engage the ratchet wheel 12,so that when the gear wheel is rotated in one direction, the same willturn the disk 9, but when the same is turned in the opposite directionthe disk will remain stationary.

Rotata'bly mounted above and in rear of the fixed shaft 8 are a pair ofspaced parallel shafts 15 and 16 respectively. The shaft 15 is'journaled as at 17 in the side walls of the casing 2 and has aplurality of spaced sprocket Wheels 18 rotata'bly mounted thereon. Thesesprocket wheels increase in size from the right to the left and arearranged according to the value of the coin deposited. Each ofthesprocket wheels 18 has a chain 19 trained around the same and thesechains are also made larger or smaller and are arranged according to thevalue of the coin deposited. These chains each carry a lower floatingsprocket wheel 20, which carries a stub shaft 21 having loosely mountedthereon the depending yoke 22, which has a weight 2-3 secured thereto.The weight tends to keep the chain 19 in an extended position. A clutchsection 24 is formed on each of the sprocket wheels 18 and is adapted tobe engaged by a cooperating clutch section 25 splined on the shaft 15and these clutch sections carry a yoke 26 slidablymounted in a grooveformed in the same. The yokes 26 are adapted to be operated by amechanism which will be hereinafter more fully described. A relativelylarge gear wheel 27 is keyed on the shaft 1'5 and engages a relativelysmall gear 28 rotatably mounted upon the shaft 16. This small gear 28carries a spring pressed pawl 29, which engages a ratchet wheel 30 keyedto the shaft 15, and when' the shaft 16 is rotated in one direction, thesmall gear will rotate therewith and rotate the large gear 27 and theshaft 15, but when the shaft 16 is rotated in the opposite direction,the gear 18 will remain idle. A pawl 31 is arranged opposite to the pawl29 and engages the periphery of the gear 28 and positively prevents thegear from rotating-in the opposite direction.

A pinion 32 is keyed to the shaft 16 and engages the rack bar 4 on thepump stem 3 and when the shaft 16 is rotated in a counterclockwisedirection the pump stem will be drawn up and the liquid forced from thecylinder, (not shown), of the pump and the shaft 15 is rotatedtherewith. and when the shaft 16 is left free the pump stem will bereturned to its normal position by gravity, and the shaft 16 will berotated in a clockwise direction and the gear 28 will. remain idle onthe shaft 16 owing to the ratchet and pawl connections 29 and 30, asclearly shown in Fig. 6 of the drawings.

One end of the shaft 16 is journaled in one end wall of the casing 2 asat 33 and the opposite end is rotatably mounted in the crank 34, whichis journaled in the opposite end wall of the casing 2 as at 35. Thecrank 84 projects outwardly from the casing 2 and carries a handle 36,whereby the same can be rotated, and the inner end of the crank carriesa rigid clutch section '37 which is adapted to be engaged by a slidingclutch section 38 splined to the shaft 16. This clutch section 38 has agroove 39 formed therein in which is slidably seated the yoke 40 whichis operated by a mechanism, which will be hereinafter more fullydescribed.

A pair of spaced contacts 41 and 42 are se cured to the lower face ofeach one of the clutch chutes 7 and are curved arcuately in a rearwarddirection from the chutes and these contacts are insulated from eachother by a non-conducting block 43 and when a coin. is dropped in one ofthe chutes this gapis bridged and a circuit is closed. The current flowsfrom a battery 44 or other electrical source through a lead. Wire 4.5 toa solenoid 45 and then through a connecting wire 46 and then through thecontacts 42 and 41 and through the lead wire 47 back to the battery.When the solenoid 45 is energized this draws its core 48 upward, whichthrows the clutch section 25 in engagement with the clutch section 24,as the core has connected thereto by means of a pin 49 which extendsthrough a slot 50 formed in the enlarged head 51 a pair of pivoted links52. One of the links is pivotally secured to the yoke 26 and theopposite link is pivotally secured to a projecting ear 53 carried by acollar 53 which is secured to the easing 2 and helps to support theshaft 15 and.

as the core 1s drawn upward the links 52 are extended and the clutchsection 25 is thrown in engagement with the clutch sec- 1 tion 26. Thereare four of the solenoids 48' in number and one of the same ispositioned below each of the sprocket wheels 18 andthey operate theclutches 24 in the manner they are in is closed. The core 48 carries acontact 54 and when the same is drawn up out of the solenoid 45, thesame makes a connection at 55 with a contact 56 which is connected to alead wire 56, which leads to the solenoid 57 and the same is connectedto a second lead wire 58 which is connected to the lead wire 47 and thusthe second solenoid is energized when the core 48 of the solenoid 45 isdrawn upward. When the solenoid 57 is energized its core 58 is drawnupward and this core has pivotally connected thereto a pair of pivotedlinks 59 which are adapted to slide the clutch section 38 in engagementwith the clutch section 37 of the crank 44, and lock the same to theshaft 16, whereby upon rotation of the crank 34 in a counter-clockwisedirection the shaft 16 will be rotatedand the pump stem '3 drawn up andthe shaft 15 and the sprocket wheel 18 which has been locked theretowill be rotated therewith. The links 59 are pivotally connected to eachother by a pin 60 which extends through a slot 61 formed in the enlargedhead 62 of the core 58 and one of the links is pivotally secured to aprojecting ear 63 formed on a collar 64 carried by the bracket 65secured to the cats ing 2 and the other link is pivotally secured to theyoke 40 carried by the clutch section 48, and when the core is drawnupward the links will be extended and the clutch section will be forcedinto engagement with the clutch section 37.

\ In order to save the current from the battery 44, each of the cores 48and 58 carry an outstanding conducting arm or armature v66 which areadapted 'to engage a pair of holding magnets 67 and as the cores of thesolenoids are drawn up, the circuit is automatically broken at thebottom of the splenoids as at 68 and these-magnets are adapted to holdthe cores in their extended positions, until the main circuit is broken.A wire 69 extends from the line wire 46 to the bottom of one of theholding magnets 67 and the top of the magnets has a wire 70 leading tothe battery wire 45 and then to the battery and the opposite magnet hasa branch wire 71 connected to the wire 70 and thus to one terminal ofthe battery and has a second wire 72 leading to the wire 69 and thus tothe other terminal of the battery. This wiring diagram is clearlydisclosed in Fig. 7 of the drawings.

The sprocket chains 19 carry a projecting lug or finger 73, which isadapted to engage a pivoted. lever 74. There are four of these levers innumber and they are positioned directly in front of the sprocket wheels18 and they are pivotally mounted as at 75 on a fixed shaft 76 which issecured to the side walls of the casing 2. These levers have arelatively long downwardly extending arm 77, each of which carries atits free lower 'end, a segmental wheel 78 which is adapted to engage thegear wheel 13 that is rotatably mounted upon the hub of the disk 9 andwhen the upper horizontal arm of the lever is struck by the upwardmovement of the projecting lug 73, the segmental wheel 78 is movedinward which rotates the gear 13 and this gear through the medium of thepawl 14 and ratchet wheel 12, rotates the disk one-third of'a turn. Abracket 79 extends downward from the top of the casing and carries aprojecting arm 80 to which is secured a contractile coil spring 81. Thiscontractile coil spring is secured as at 82 to the lever 74 and returnsthe same to its initial position. When the lever 74 returns to itsnormal position it rotates the gear 13 in a counter-clockwise direction,which fails to move the disk 9 as the dog 14 rides over the ratchetwheel 12. When the disk 9 is turned the one-third of the revolution, thesame carries the coin from the chute 7 and the coin rides over a cam 83which forces the coin out of the slot 10 of the disk. this construction,it can be seenthat when the chain makes one revolution the circuit isopen which allows the cores 48 and 58 to return to their normal positioncarrying the clutches out of engagement with the rigid .clutch sectionsand thus preventing any the coin from the contacts 41 and 42.

clutch sections which locks the crank 34 to the shaft 16 and one of thesprocket wheels 18 on the shaft 15. The pump stem 3 can then be forcedupward through the ,medium of the pinion 32 by the crank 34, which willalso rotate the shaft 15 and one of the sprocket wheels 18, which willrotate the chain 19 therewith and when the chain has made a completerevolution, the same, through the medium of the projecting lug 73 willoperate the lever 74 and thus mqg e IV making the chains 19 longer orshorter, more or less of the liquid being dispensed can be given for acertain coin according to the rise and fall of the price of the liquid.

In Fig. 10 is shown a slightly modified form of the device and in thisform the method of rotating the disk 9 as shown in Fig. 4 is dispensedwith and a ratchet wheel 84 is rigidly secured to the disk 9, which isengaged by a pawl 85 pivotally secured to the end of the arm 86, whichtakes the place of the arm 77.. The arm 86 is slidably mounted between a.pair of guides 87 and has its upper end pivotally secured to the outerend of a lever 88, which is used instead of the arm 74. The lever 88 ispivotally mounted intermediate its ends as at 89 and the inner end isadapted to be engaged by the lug 73, the contractile coil spring 81normally holds the inner end of the lever 88 in lowered position andwhen the lug 73 engages the same, the inner end will rise upward, whichwill slide the arm 86 downward and the pivoted pawl 85 will ride overthe teeth of the ratchet wheel 84 and when the lug 73 rides past thelever 88 the spring 81 will force the. lever 88 downward and raise thearm 86, which will allow the pawl 85 to catch in a tooth of the ratchetwheel 84 and turn the same the desired fraction of a revolution. Asecond pawl 90 engages the ratchet wheel 84 and prevents rotation of thesame in a rearward direction.

In practice, we have found that the form of our invention, illustratedin the accom panying drawings and referred to in the above .description,as the preferred embodiment, is the most efficient and practical; yetrealizing the conditions concurrent with the adoption of our device willnecessarily vary, we desire to emphasize the fact that various minorchanges in details of construction, proportion and arrangement of artsmay be resorted to, when required, wit out sacrificing any of theadvantages of our invention as set forth.
